Good luck took me 5 months to find one last summer. Keep an eye on the Ruby trucks website they used to sell them then they started selling those supplier I’m not sure if they are selling them out right again or not. Also Amerikaz most wanted.
My factory cooler lasted 10 years and 180k miles baking in the oven so I put another in. I put stock plugs back in as well. First set at 100k miles. Second set because it was appart. No injector issues at 180k so I would not mess with them with low miles like yours. Your engine will likely poop...
I was referencing stock leaf packs, I loved my BDS springs, and RE. The mil wrap is the best there. If you are getting wrap with t BDS then build or buy the torque arm.
YJ leafs have no main eye support. They flex well but the lack of support enables it to bend main leaves easily, enduce axle wrap and wheel hop.
Adding a second leaf to support the main helps drastically.
Nice work! I have been wanting to build one for a long time as I have been just using a Plug and my drill battery one wire at a time.
You should probably label them by function; as that is standard. The wire colors change between utility and RV trailers. See the diagrams...
